  • Patent number: 8387752
    Abstract: An anchor system for a utility pole that temporarily prevents falls by a utility worker. The system has a bolt and a head formed on one end and a threaded shank that extends through a utility pole and exposed on one surface of the pole. A concave saddle washer is attached to the bolt that rests against the pole's outer curved surface. A concave saddle plate located on the end of the bolt opposite the saddle washer rests against the opposite surface of the pole. An optional nylon sleeve is disposed between the ring member and the hinge plate to reduce sounds and interference. In one embodiment, the ring member freely pivots on the hinge plate. In another embodiment, the ring member is held in a diagonal position of the hinge plate until a free-fall force is exerted thereto that causes the ring member to move to a longitudinal position.
